Abstract: A valve comprising a valve body (10) having a through opening (22) that forms a fluid passage and having a wall (24, 26) surrounding a portion of the fluid passage, the wall defining a radially inwardly facing surface, the valve further including a valve element (28) rotatably mounted in the valve body. To retain a valve seat in the valve body, there is provided a ring (92) that has a peripheral surface (94) shaped and sized such that the peripheral surface closely faces the radially inwardly facing surface of the wall when the ring is positioned within the through opening. The ring has a first axially facing side (95) and a second axially facing side and a notch (93) formed in the first side, the ring also having a second, radially outwardly facing annular groove (96) in the peripheral surface that intersects the notch. When the ring is positioned within the through opening of the valve body, the first and second annular grooves are in register and thereby define an annular channel. A wire member (98) having a first and a second end retains the ring in the valve body.

Patent CA-2196711-C (CA)
Inventor: BROWN DAVID M
IPC: E21B7/28
Filed: 1997-02-04
Granted: 2001-09-18
Abstract: This invention relates to installing sections of horizontally laid underground piping using a coring rod to pull or push a coring knife horizontally through the site.   During tunnel diameter enlargment, when the coring knife is pushed into the exit pit, the coring rod and coring knife will fall to the exit pit's bottom. The invention is a coring rod support wheel that has a relatively large smooth outer surface and a hollow hub rigidly held within it. The axis of the hollow hub is parallel to the axis of the wheel, but not necessarily the same as the axis of the wheel. The diameter of the hub allows a coring rod to slide freely through it. Once the coring rod has been slid through the hub, the coring rod and any attached coring knife are supported and guided by the wheel to prevent them from falling to the exit pit's bottom, and to keep them on the correct path during tunnel diameter enlargment.

Abstract: A flexibly-mounted active vibration absorber (AVA) which has a secondary controllable mass M3. If the passive resonance of mass M2 of the tuned absorber is insufficient to control the input vibration, a secondary mass M3 is vibrated at a frequency, amplitude and phase sufficient to make up the deficiency in mass M2. Many embodiments are described which depict variations on the first spring used for flexibly mounting the AVA, the actuators used to drive the AVA, and the attachment features for attaching to a vibrating member. Further, in another aspect, means for counterbalancing the moments produced by the AVA are described.

Title: System and method for earth probing with deep subsurface penetration using low frequency electromagnetic signals
Inventor: BROWN RUSSELL D
IPC: G01S13/88
Filed: 1994-10-17
Granted: 1999-08-31
Abstract: An earth probing system uses deep penetration of electromagnetic waves into soil and other media. Advantage is taken of lower attenuation of radar waves in soil by frequencies of about three megahertz or less. Bursts of electromagnetic energy of various frequencies in this range are consecutively transmitted. The transmitting antenna (118) is continuously tuned, so as to maintain resonance during each burst, allowing large circulating currents and high power output. In a receiving antenna system, a dual antenna arrangement (111, 112) is providing for obtaining improved reception. A corresponding dual antenna circuit employs "spatial notch filtering", automatic adjustment of antenna gain-frequency variations, as well as compensation for transmitter gain variation. The system may be implemented in a totally analog, totally digital, or hybrid manner. Preferably, a signal processing method detects and digitally samples signals reflected from subsurface layers and buried objects (316, 316'). The invention provides means for removing system distortions and interfering signals, for compensating for aliasing errors and frequency-dependent antenna gain and phase variations, and for avoiding masking errors introduced by strong reflections.

While the sensor is moved in a horizontal direction perpendicular to the optical axis of the sensor light, the distance to each of a plurality of measurement points arranged horizontally at regular intervals along a line that runs on said pile of the powdery or granular material so as to face the movement path of the sensor. This step is performed every time the sensor is moved vertically a predetermined distance at a time. In each session of the step, a point is extracted that is closest to the sensor, and a function describing a straight line approximating the curve through all of the thus extracted points is determined by the least-squares method. Then, the angle of this straight line with respect to a horizontal plane is determined.

Abstract: An overfill preventing valve is adapted to be operatively interposed in a flow path between a fluid source and a compressed fluid storage cylinder to prevent the cylinder from being overly filled. The improved valve includes an elongated tubular body having a first seat a first space a second space a second seat a third space a third seat a fourth space and an entrance portion communicating with a source. A passageway continuously communicates the first and fourth spaces. The second and fourth spaces communicate with the interior of the cylinder. A float is contained within the body for movement toward and away from the first seat in response to the liquid level in the cylinder. A valve member is mounted on the body for sealed movement toward and away from the second seat. This valve member separates the first space from the second space. The valve member is biased to move away from the second seat. A piston separating the third space from the fourth space, is mounted for sealed sliding movement therealong toward and away from the third seat. The piston is biased to move toward the third seat. The piston has a variable-area orifice communicating the entrance portion with the third space. The cross-sectional area of this orifice varies as a function of the direction of the flow. When it is desired to fill the cylinder and the float does not engage the first seat, incoming fluid displaces the piston away from the third seat and flows from the entrance portion into the cylinder via the fourth space. However, when the float sealingly engages the first seat, the valve member is caused to sealingly engage the second seat, and the piston is caused to sealingly engage the third seat to prevent further incoming flow from the source to the cylinder.
